Description

Raw Pygas from the steam cracking process is first fed to the first stage hydrotreating section. To produce BTX, this C6+ Stream is sent to a fractionation section to obtain a C6-C8 Heart Cut, which will be further hydrotreated to saturate mono-Olefins in the second stage hydrotreating section. The hydrotreating unit consists of three Sections: 1) First stage hydrotreating section to saturate mainly di-Olefins to Olefins. 2) Second stage hydrotreating section to saturate the Olefins and de-sulfurize the Pygas. 3) Fractionation section to stabilize the Hydrotreated Streams and to recover the C6-C8 Heart Cut for further processing for Aromatics extraction. The C9+ Raffinate, or C9+ Cut, is the heavier Bottom Fraction from the fractionation process.
